Title:
METHOD FOR DETERMINING CALIBRATION PARAMETER AND MOBILE DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/113381
Kind Code:
A1
Abstract:
A method for determining a calibration parameter and a mobile device. The method is applied to a mobile device comprising a sensor to be calibrated, is used for increasing a correlation between the calibration parameter and the temperature and reducing errors of the sensor caused by temperature drift. The method comprises: obtaining at least three different groups of output data of a sensor to be calibrated collected in a temperature range, wherein the at least three different groups of output data are collected when the mobile device is in a static or quasi-static state, and the quasi-static state indicates a motion state in which the motion amplitude is less than a preset value; and determining, according to the at least three different groups of output data, the calibration parameter used by the sensor to be calibrated in the temperature range.
